JOSEPH BUTCHER, OF MELROSE, MASSACHUSETTS.

CYCLOMETER.

SPECIFICATION forming part of Letters Patent No. 522,965, dated July 17,1 894.

Application filed June 23, 1 8 9 3- To ctZZ whom it may concern.-

Be it known that I, J OsEPH BUTCHER, a citizen of the United States, anda resident of Melrose, in the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements inOyclometers, of whichthe following is a specification.

My invention relates to that class of devices commonly calledcyclometers and odometers which are mounted on and are carried around bythe wheel or other rotating part of a vehicle and the registeringmechanisms of which are actuated by the force of gravity operatmg toshift some moving part usually arranged within the cyclometer case, asthe wheel or other rotating part revolves. In all cyclometers of thisclass so far as I am aware, a pendent weight is attached which is oflittle utility and adds an undesirable weight to the cyclometer.

The object of my present invention is to dispense with the pendentweight and to place the cyclometer on the wheel or other rotating partof a vehicle, so that it shall be actuated intermittently by themovement of the wheel or other rotating part one or more times durmgeach rotation of one of the wheels or other rotating parts of thevehicle. My invention will be fully described hereinafter and its novelfeatures carefully defined 1n the claims. In the drawings which serve toillustrate my invention, I have for convenience shown its novel featuresembodied 1n a bicycle crank cyclometer having registering mechanismsubstantially identical with that illustrated in Letters Patent N o.356,?)22, dated February 1, 1887.

Flgure 1 is a front view of the cyclometer showing the dial and clampfor attachment to the crank. Fig. 2 is a rear view showing the clamp forattachment to the crank. These are merely exterior views. Fig. 3 is aback or rear View of the internal mechanism of the cyclometer. This viewshows the cyclometer as it stands when the crank to which it is securedstands nearly horizontal. Fig. 4 is a similar view to Fig. 3 but showingthe position of the cyclometer when the crank to which it is attachedstands nearly vertical. Fig. 5 is a side view of the cyclometer. Fig. 6represents, in detail, plan and side views of the weight supportinglink.

Serial No. 4'7 8,576. (No model.)

Fig. 7 is a section on line 77 of Fig. 4,looking in the direction of thearrows, the mechanism being removed from the case. Fig. 8 is aperspective view of the mechanism enlarged, some of the parts beingseparated from the others.

For convenience I prefer to inclose the registering mechanism in acircular sheet metal case and this case I close hermetically. The dialconstruction, units, tens and hundreds, disks, ratchets and train ofgearing are in substance the same as those described in my LettersPatent before mentioned and need no particular description. In fact theregisterlug mechanism may be constructed in any .way so long as it iscapable of being actuated intermittently by a pawl and ratchet movement.I

The novel features of my present invention relate to the means forimparting a rotaryoscillatory motion to the leading or driving wheel ofthe registering mechanism and this wheel may be made to impart itsmovement to said mechanism in any of the well known ways.

A represents the case of the cyclometer; B, the dial plate; 0, a clampof any kind for attaching the cyclometer to a crank Din this casesupposed to be the crank of a bicycle.

Referring now to Figs. 3 and 4, a, is a driving'wheel of the registeringmechanism which in this case is a ratchet wheel. This wheel may impartits movement to the indicator of the cyclometer by any suitablemechanism. My object is to impart an intermittent forward motion to thiswheel and I will now describe the meansI employ for effecting thisobject.

I), is a weight having a link 0 connected to one end to support andguide it in its operative movements, as will presently appear. This link0 has a sleeve d at one end loosely mounted on a pin e supported by thedial and frame bar 70', and at the other end has a sleeve or bearing fto receive a pin g connecting it with the weight, as shown. Said weightb is of an irregular form, consisting of two parts it and '5 connectedby a reduced portion 70, and it is held in position by the frame bar 70'of the mechanism passing across said reduced portion, and is providedwith a bearing 1) in the center of said reduced portion to receive acrank pin Z, and said crank pin Z is con neeted with ratchet wheel a,mounted freely on pin 0, connected with the frame work of the mechanismand having a spring detentn'. 5 Suppose the crank D, to which thecyclonicter is attached to be revolving in the direction of arrow 00, inFigs. 3 and i; when it reaches a nearly horizontal position, as shown inFig. 3, the weight b, will be at the extreme lowest position in itscase, but as it continues to revolve until it reaches a nearly verticalposition, as shown in Fig. 4; the action of gravity on the weight Z),will cause it to seek the position shown in Fig. 4:, and will r5 bringthe eye-piece or pawl 17, into engagement with the ratchet wheel a. Inmaking this movement, it will be seen that when the weight 7), movesunder the impulse of gravity, it is limitedin its movement laterally andvertically by the action of the erank-pinZ working in bearing in reducedportion 7c, and attached to the wheel 41, mounted on-the frame work ofthe mechanism and that said weight I), will impart one impulse to theratchet wheel a, by means of the eye-piece or pawlp,

projecting from said weight. Each revolution of the crank D,imparts oneforward impulse to the wheel a.

The link and sleeve connection described 0 permits the weight to havethenecessary movement on the crank pin Z, the weight being prevented fromrotating on an axis relatively to the ease. The pin Z on the wheel at isfor the purpose solely of guiding the weight so that 5 the pawl 13 willdescribe an orbital path and make contact with the ratchet wheel onceduring each orbital movement described by that portion of the weight towhich the pawl 21 is attached.

An important feature of my invention resides in the rotary-oscillatoryweight Z), by which initial movement is imparted to the train of gearingwhich actuates the indicator of the cyclometer.

I do not wish to limit myself to the mechanism shown, as theintermediary between the oscillating and rotating weight and the wheel(L, as this may be varied almost indefinitely without departing from thetrue spirit of my invention. Ihave shown a simple and operative device,butt am aware that the motion of the weiglit Z2, may be communicated tothe wheel a, in various ways.

Having thus described my invention, I claim 1. A cyclometer comprisingin its construction a casing, an indicator, a train of gearing foroperating the indicator, a ratchet wheel for imparting movement to saidtrain of gearing,

a weight bodily movable within the casing and having a pawl attachedthereto, and supporting and guiding devices for the weight of astructural character in virtue of which the pawl is adapted to move inan orbital path ad jacent to the ratchet wheel and engage it once duringeach complete movement of the weight relatively to the casing,substantially as de scribed.

2. A cyclometer comprising arbor c, link (2, sleeves (Z andf, crank-pinZ, ratchet wheel w, pin 0 and an actuating weight, substantially as andfor the purposes set forth.

3. The combination, with the registering mechanism of a cyclometerhaving a driving ratchet wheel a, of a ratchet wheel a mounted on pin 0and having pin Z, an actuating weight Zrhaving pawl p and connected by alink 0 and sleeve (Z, with an arbor 6 attached to the frame work of saidregistering mechanism, said link and sleeve, crank pin, ratchet wheeland pin guiding and limiting the movement; of said weight whereby themovements of said weight are communicated to said pawl.

4. The combination with the crank or other rotating part of a vehicle,of a registering mechanism adapted to operateintermittently and anactuating weight connected, at one end, by a crank-lever and sleeve withan arbor connected with the frame work of said mechanism, and connected,at another end, by a crank-pin and a ratchet wheel pinioned to the framework of said mechanism, as set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 12th day of June, A. D.1893.
